CAR-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 595,127, dated December'7, 1897.

Application filed February 9, 1897. Serial No. 622,619. (No model.)

To 64% whom it may concern:

Be it known that 1, ANDREW J. MOARTHUR, of Gainesrille, in the county ofAlachua and State of Florida, have invented new and useful Improvementsin Car Ventilators, of which the following is a full, clear, and exactdescription.

This invention relates particularly to ventilators forrefrigerator-cars, and the object is to provide a simple and strongventilator so arranged that it may be elevated in sections in eitherdirection with relation to the hatchway and that may be swung whollyaway from the hatehway.

I will describe a car-ventilator embodying my invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a plan View of a portion of the roof of a car and showing aventilator embodying my invention. Fig. 2 is a section showing theventilator in one position, and Fig. 3 is a section showing theventilator in another position.

Referring to the drawings, 1 designates the roof of a car, having ahatchway 2 communicating with the interior of the car and having itswalls extending above the roof. Hinged to one side of the hatchway 2 isa frame 3, to which is attached a screen 4.. The hinge connection isshown at 4.

Removably mounted on the frame 3 is a cover consisting of two sections 5and 6, hinged at their inner edges to a partingstrip 7. These sections 5and 6 have downwardlyextended side pieces and downwardly-extended endpieces which engage against the outer sides of the frame 3. Hinged toone of the cover-sections is a bar 8, having a hook 9 at its free endadapted to engage with a hook 10 on the other section.

It is desired that the frame 3 may be con nected to the cover-sectionsso as to be moved therewith, as indicated in Fig. 8. The means ofconnection, as here shown, consists of stapies 11, extended throughopenings in the cover-sections and designed to be engaged by pins 12,having chain connection with the cover-sections.

In operation when it is desired to elevate one section of the cover itis drawn upward, as indicated in Fig. 2, and the hook 9 engaged with thehook 10. Of course when the parts are in this position the frame 3 andits screen 4 will remain in the hatchway. Should it be desired to raisethe entire cover and the screen so that ice maybe passed through thehatchway, the screen-frame will be secured to the cover-sections bymeans of the pins 12, and then the cover and screen maybe swung upwardand the end of the rod 8 engaged with astop-piece 13 011 the roof of thecar, as shown in Fig. 3.

In Fig. 2 I have shown the section 5 as elevated and the section 6 asclosed, but it is obvious that this order may be reversed, dependingupon the direetion in which the car is moving. It is obvious that whenthe section 5 is closed the section 6 may be held open by the bar 8.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A car-ventilator, comprising a hatchway, a framehaving hinge connection at one side of the hatchway, a screen secured tosaid frame, a cover consisting of two sections hinged to swing onesection relatively to the other, and means for holding either one ofsaid sections in an open position, substantially as specified.

2. A ear-ventilator, comprising a hatchway having its walls extendedabove the roof of the car, a frame hinged to said hatchway, a screencarried by the frame, a cover consisting of two sections hinged to swingone relatively to the other, means for removably securing said sectionsto the frame, and a rod having a hinge connection with one section ofthe cover, and having a hook at its free end to engage with a hook onthe other section of the cover, substantially as specified.

3. A car-ventilator, comprising a hatchway having its walls extendedabove the roof of the car, a frame having a hinge connection With a wallof said hatohway, a cover consistone of the cover-sections, and meansfor ening of two sections hinged toswing, one relagaging" the free endof said rod with the other tively to the other, staples on the framedesection of the cover,substantial1y as specified. 1o signed to extendthrough openings in the ANDREW J. MOARTHUR. cover-sections, pins forengagin g through said \Vitnesses:
